Referring to fig. 5-7, the folding mechanism 40 includes a folding lifting bar 41 and a sliding sleeve 42 fixed thereto, the sliding sleeve 42 is slidably connected to the front leg 12 and fixed to the connecting member 32, so that when the folding lifting bar 41 is pulled downward, the sliding sleeve 42 drives the connecting member 32 to slide, and the connecting member 32 drives the engaging member 31 to slide to the second position to unlock the first locking mechanism 30.

In addition, a pivoting piece 411 is protruded from the retracting lever 41 for pivoting the second locking mechanism 50, as described in detail below.

Referring to fig. 1-4 again, in another embodiment of the stroller 1 provided in the present invention, the stroller 1 further includes a second locking mechanism 50, and the rest of the structure is completely the same as the above embodiment, and will not be described again. Specifically, the second locking mechanism 50 is disposed on the folding mechanism 40 and detachably abutted against the frame 10, and is used for locking the frame 10 in the unfolded state, and when the second locking mechanism 50 is unlocked, the folding mechanism 40 is operated to drive the first locking mechanism 30 to unlock, so as to fold the stroller 1, and the two locking mechanisms are disposed to enable the stroller 1 to be locked more safely.

Referring to fig. 5-6, the second locking mechanism 50 is rotatably connected to the retracting lever 41 and has a locking position and a releasing position, when the second locking mechanism 50 is in the locking position, the second locking mechanism abuts against the basket pipe 14, so that the retracting lever 41 cannot be operated, when the second locking mechanism 50 rotates to be disengaged from the abutting against the basket pipe 14, the second locking mechanism is in the releasing position, and then the retracting lever 41 can be pulled downward to slide to drive the first locking mechanism 30 to release the lock.

Referring to fig. 7, the second locking mechanism 50 includes a safety lock 51 pivotally connected to the folding lifting rod 41 and an elastic member 52 disposed on the safety lock 51, wherein the elastic member 52 is connected to the pivot shaft of the safety lock 51 and provides an elastic force for the safety lock 51 to abut against the basket pipe 14. The safety lock 51 includes a first contact end 511 and a second contact end 512 arranged at an included angle, a connection portion of the first contact end 511 and the second contact end 512 is pivotally connected to the pivot piece 411 of the folding lifting rod 41, a groove 511a matched with the basket pipe 14 is concavely arranged at an end portion of the first contact end 511, and the elastic member 52 is connected to the pivot shaft of the safety lock 51. As shown in fig. 5, when the safety lock 51 is in the locking position, the groove 511a of the first contact end 511 is engaged with and abutted against the basket pipe 14, the side of the second contact end 512 is abutted against the folding lifting bar 41, and the elastic force provided by the elastic member 52 keeps the safety lock 51 in the locking position; as shown in fig. 6, when the safety lock 51 is rotated, the first contact end 511 is disengaged from the basket pipe 14, and the second contact end 512 is disengaged from the foldable lifting bar 41, the safety lock 51 is in the unlocking position, and the foldable lifting bar 41 can be pulled to slide downwards to drive the first locking mechanism 30 to unlock.

Preferably, the elastic member 52 is a torsion spring, but is not limited thereto, and other elastic members may be used.

In addition, referring to fig. 3-4 again, the elongated slot 311 is formed on the engaging member 31, the connecting member 32 is inserted into the elongated slot 311 and passes through the first through hole 171 and the second through hole 121 to be fixedly connected with the sliding sleeve 42, and the elongated slot 311 prevents the second locking mechanism 50 from interfering with the basket pipe 14 to hinder the unfolding of the frame 10 during the unfolding of the frame 10, so that the frame 10 can be unfolded more smoothly.

The folding operation of the stroller 1 according to the second embodiment of the present invention will be described with reference to fig. 1 to 10.

As shown in fig. 1-2 and 8, when the stroller 1 is unfolded, the first locking mechanism 30 and the second locking mechanism 50 lock the stroller frame 10, specifically, the engaging member 31 of the first locking mechanism 30 is engaged with the engaging notch 181 of the second pivot joint 18 (see fig. 4), and is always kept at the first position under the elastic force of the reset member 33, and at the same time, the safety lock 51 of the second locking mechanism 50 is abutted against the basket pipe 14 (see fig. 2), so as to perform a second safety lock function on the stroller frame 10, and the locking function of the first locking mechanism 30 and the second locking mechanism 50 can ensure the stability of locking the stroller frame 10, and thus the stroller frame can be used more safely.

When the stroller 1 needs to be folded, firstly, the second locking mechanism 50 is unlocked by operating, that is, the safety lock 51 is rotated to disengage the first contact end 511 from the basket tube 14 and disengage the second contact end 512 from the folding lifting rod 41 (see fig. 6), at this time, the safety lock 51 is in the unlocking position, the folding lifting rod 41 can be pulled downwards, the folding lifting rod 41 drives the sliding sleeve 42 to slide downwards along the front leg 12, the sliding sleeve 42 drives the engaging member 31 to slide downwards along the front leg 12 through the connecting member 32, the restoring member 33 is compressed in this process, when the engaging member 31 is disengaged from the second pivot joint 18, the first locking mechanism 30 is in the unlocking state, the folding lifting rod 41 is pulled upwards, the hand 11 can be pushed to pivot downwards around the pivot axis between the hand and the front leg 12 under the action of the self gravity of the component, as shown in fig. 9, the hand 11 drives the front leg 12 to pivot downwards during the downward pivoting process, and the hand 11 and the front leg 12 are both drawn towards the rear leg 13 to fold the frame 10 to the state shown in fig. 10, the folded frame 10 has a small volume, and is convenient to fold and operate and smooth in folding process. In addition, the seat 20 can be folded together with the frame 10 during the folding process of the frame 10, which is a conventional arrangement in the art and will not be described in detail.

When the stroller 1 needs to be unfolded again, the rider 11 is pushed to pivot upwards, the rider 11 drives the front leg 12 to pivot forwards, when the rider 11 pivots from the state shown in fig. 10 to the state shown in fig. 8, the engaging member 31 of the first locking mechanism 30 automatically snaps into the engaging notch 181 of the second pivoting joint 18 (see fig. 4) under the elastic force of the reset member 33, so as to lock the first locking mechanism 30, and in the unfolding process of the stroller frame 10, if the safety lock 51 of the second locking mechanism 50 interferes with the basket tube 14, the connecting member 32 can move along the long groove 311 of the engaging member 31, so that the stroller frame 10 can be unfolded smoothly.

In summary, the stroller 1 of the present invention has the first locking mechanism 30 and the folding mechanism 40, the first locking mechanism 30 is disposed on the frame 10 for locking the frame 10 in the unfolded state, and the folding mechanism 40 is movably disposed on the frame 10 and connected to the first locking mechanism 30 for driving the first locking mechanism 30 to unlock, and when the stroller needs to be folded, the folding mechanism 40 is pulled downward to drive the first locking mechanism 30 to unlock, so that the stroller 1 can be folded, the folding operation is smoother, and the folded stroller 1 has a smaller volume. Furthermore, the stroller 1 is further provided with a second locking mechanism 50, the second locking mechanism 50 is disposed on the folding mechanism 40 and detachably abutted against the frame 10, so as to further lock the frame 10 in the unfolded state, so that the stroller 1 is more safely locked, after the second locking mechanism 50 is operated to be disengaged from the abutment against the frame 10, the folding mechanism 40 is pulled downwards to drive the first locking mechanism 30 to unlock, and the folding operation is convenient.

The structure of the rest of the stroller 1 according to the invention is well known to the person skilled in the art and will not be described in detail here.
